Price Tracker Chrome Extension Generator
Price trackers combine a content script (read the price from the page), storage (history), and alarms (periodic re-checks). This generator wires all three.
Edit the prompt — it's just a starting point.
What gets generated
- JSON-LD first price detection, CSS-selector fallback
- chrome.alarms background re-checks (service-worker safe)
- Desktop notification on a price drop
- Price history persisted in chrome.storage.local

Can a service worker run a timer?
No — MV3 service workers are terminated when idle. The generated extension uses chrome.alarms, which wakes the worker on schedule.
